21 MPG combined is a difficult reality for the 2021 Acura TLX Type-S with the performance tire package. This isn’t a commuter car; it’s a driver’s car, built to deliver exhilarating performance and engaging handling, and a visceral driving experience takes priority over squeezing every last drop of fuel. Buyers choosing this specific version of the TLX understand, and largely accept, the tradeoff. They’re willing to pay a premium at the pump for the superior power, enhanced grip, and overall dynamic capabilities that define the Type-S experience.

City and highway performance

The EPA estimates 19 MPG in the city and 24 MPG on the highway for the TLX Type-S with performance tires. The lower city figure reflects the nature of stop-and-go driving, where the turbocharged 3.0L V6 spends more time idling and accelerating than cruising at a steady speed. The highway figure, while better, is still relatively modest for a modern sport sedan. This is due to the engine’s focus on power delivery, the added rolling resistance of the wider, stickier performance tires, and the weight of the car itself, which contributes to higher fuel consumption at higher speeds.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2021 Acura TLX Type-S with performance tires is $2,750. This figure is based on driving 15,000 miles per year and using national average fuel prices. This figure is a benchmark, not a guaranteed expense; actual fuel costs can vary significantly depending on driving habits, local fuel prices, and the type of fuel used. Drivers with a heavier foot or those who live in areas with high gas prices should expect to pay more. You can view all Acura fuel economy data right here at FuelEconomyHub.com.

Real-world expectations

While the EPA estimates provide a baseline for comparison, real-world fuel economy can differ. Aggressive driving, frequent use of the car’s Sport+ mode, and navigating congested city streets will all negatively impact fuel efficiency. Conversely, drivers who prioritize smooth acceleration, consistent speeds, and make use of the car’s comfort mode can expect to see figures closer to, or even slightly above, the EPA estimates. Keep in mind that tire pressure plays an important role; maintaining the recommended pressure will help to maximize fuel economy and prolong tire life.

How it compares

The Acura TLX Type-S isn’t the only sport sedan available. The BMW M340i, for example, is rated at 26 MPG combined. The Audi S4 achieves 24 MPG combined. The Mercedes-AMG C43 lands in-between at 22 MPG combined. These differences, while seemingly small on paper, can add up over time. Buyers who are particularly sensitive to fuel costs may find these alternatives more appealing, provided that those models meet their other performance and luxury requirements. Comparing the TLX MPG across all years can also offer valuable insights.

Tips to maximize efficiency

While the TLX Type-S isn’t designed for hypermiling, adopting a few mindful driving habits can help to improve fuel efficiency. Avoid aggressive acceleration and braking. The turbocharged engine responds well to smooth, gradual inputs, and unnecessary hard acceleration only burns excessive fuel.

Make use of the TLX’s drive mode selector. In Comfort mode, the car softens throttle response, optimizes shift points, and reduces steering effort to prioritize fuel efficiency and a relaxed driving experience. The less time you spend in Sport or Sport+ mode, the better your fuel economy will be.

Ensure your tires are properly inflated to the recommended pressure listed on the driver’s side door jamb. Underinflated tires increase rolling resistance, which negatively impacts fuel economy. Check your tire pressure regularly, especially during temperature changes.

Avoid unnecessary idling. If you know you’ll be stopped for more than a minute, turn off the engine. Modern cars are designed to restart quickly and efficiently, and idling wastes fuel with minimal benefit. This is particularly relevant in city driving, where prolonged stops are frequent.

Consider removing unnecessary weight. Remove any items from the trunk or back seat that aren’t essential. Extra weight requires more energy to accelerate and maintain speed, which impacts fuel economy.
